Question

Pre-Lab Questions A. In the experiment, you are instructed to use 15 mL of a 5% solution of adipoyl chloride and 15 mL of a 5% solution of hexamethylenediamine. Assuming these solutions are Reagent | Mol. Wt. | Density Adipoyl chloride | 183 g/mol | 1.26 g/mL Hexamethylenediamine | 116 g/mol | 0.89 g/mL %volume/volume, calculate the mmol of each reagent that will be used in the experiment. Which reagents is the limiting reagent? 1. What is the theoretical yield (mg) of nylon that is formed in the experiment? Since you do not know the molecular weight of the polymer, you can get the theoretical yield in mg by the following procedure: * Determine the mass of adipoyl chloride used from the mmol of the limiting reagent. * Determine the mass of the hexamethylenediamine used from the mmol of the limiting reagent. * Determine the mass of HCl lost from the mmol of the limiting reagent. * Theoretical yield of polymer = mass adipoyl chloride + mass hexamethylenediamine - mass HCl. B. In the experiment, you are instructed to use 2.0 g of a Phthalic anhydride and 0.8 mL of a ethylene glycol and 0.8 mL glycerol respectively. Reagent | Mol. Wt. | Density Phthalic anhydride | 148 g/mol | Ethylene glycol | 62.07 g/mol | 1.11 g/mL Glycerol | 92.02 g/mol | 1.26 g/mL 2. What is the theoretical yield (mg) of polyester that is formed in the experiment?
